CAR-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 632,205, dated August29, 1899. Application filed im@ 20,1899. sena No. 721,220. No inode.)

T0 all whom iz'; may concern:

Be it known that I, CHARLES REIMULLER, a citizen of the United States,residing at Belmar, in the county of Monmouth and State of New Jersey,have invented a new and useful Car-Ventilator, of which the following isa specification.

This invention relates to car-ventilators; and it has for its object toprovide, in connection with the cupola or other convenient por tion of acar, a ventilator which will not only prevent the passage of cinderstherethrough, but which will furthermore filter the air of smoke andother gases and from which the exceedingly small particles thus filteredwill be discharged.

In the drawings forming a portion of this specication and in which likenumerals of reference designate corresponding parts in both views,Figure 1 is a front elevation of the upper portion of a car providedwith a ventilator constructed in accordance with this ilnvention. Fig. 2is a section on line 2 2 of Referring now to the drawings, 5 representsthe body of a car, upon the upper portion of which is the usual cupola6. The front end of this cupola is open and is provided with a partialfilling 7, consisting of a screen of wire or other suitable materialwhich reaches from the upper wall of the opening to a line adjacent thelower wall thereof, resulting in the formation of an interspace Sbetween the screen and the lower Wall of the opening.

Arranged transversely of the forward end of the cupola is a floor 9,which extends from the interspace 8 rearwardly and slants upwardly for asuitable distance, said floor being connected at its inner edge with aframe 10, in which is pivoted a transom 11, having suitable closingmeans of usual construction. Through the medium of this transom theventilating-passage inclosed by the iioor and the sides and roof of thecupola may be opened or closed.

Intermediate the screen 7 and the transom 11 and adjacent the latter isa screen 12, mounted in a suitable frame and completely iillin g theventilatorpassage transversely and vertically.

Intermediate the screens 7 and 12 and in engagement with the latter is abody of raw cotton or other suitable filtering material, the front endof which body is separated from the screen 7 by an interspace 14,forming a chamber for purposes to be presently explained.

The operation of the device is as follows:

` When the transom 11 is in the position shown in full lines in Fig. 2',the Ventilating-passage is closed and the apparatus lies dormant. If thetransom be then opened and a draft be directed upon the screen 7, theair will pass through said screen and into the chamber 14, from which itwill pass through the filtering material 13 and the screen 12, andthence through the transomsopening and into the cupola. In the passageof the air through the screen 7 all large particles of dust and cindersare separated from the air and fall downwardly upon the water-sh'ed 16of the root' of a car, from which they are expelled. The smallerparticles which pass through the screen 7 are passed through the chamber14 and into engagement with the filtering material 13, which acts toseparate them from the air and from which they may fall upon the floorof the chamber 14. The pureairpasses rearwardly through the screen 12and transom 2 into the cupola. The floor 9 of the ventilator-passagebeing sloped outwardly and downwardly the particles which fall thereonare gradually moved in the direction of and through the inter-space 8 bythe jostling or j olting of the car. It will thus be seen that when theair has passed through this ventilator it is freed of its impurities,and, moreover, the solid portions of these impurities are dischargedvfrom the ventilator, and hence do not interfere with the effectiveworking of the device.

It will be readily understood that I may employ any desired materialsfor the dierent parts of the construction that may be found applicableand that'I may depart from the specific construction and arrangementshown without departing from the spirit of the invention.

Having thus described the invention, what is claimed is- 1. A ventilatorcomprising a passage, a screen at the inlet end of the passage separatedfrom the floor thereof by an interspace, a filtering material within thepassage and IOO and separated. from the oor by an interspaee, a secondscreen within the passage, a ltering material Within the passageengaging the second screen and separated from the iirstnamed screen byan interspaee, and an adjustable closure at the rear end of the passage.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

CHARLES REIMULLER.
